Blockchain network designs never draw in the reins of innovation. The Bitcoin network was born as a simple peer-to-peer network to store and transact value. The success of Bitcoin sowed the seeds of the Ethereum decentralized network and its smart contract capabilities and marked the birth of DeFi.

Soon, the monolithic blockchain network proved inadequate in quenching the hunger for block space. Vitalik Buterin conceptualized the scalability trilemma in the late 2010s to highlight the trade-offs between decentralization, scalability, and security. Innovators soon began experimenting with multi-layered blockchain systems that offloaded the stress of the mainnet to side chains, state channels, rollups, and lightning networks to make blockchain accessible for day-to-day transactions.

The Rise of Modularity

The blockchain community had begun to embrace the idea of a modular blockchain architecture by the early 2020s. Modularity abstracted the blockchain infrastructure into layers like consensus, data availability, and execution; decoupling these components into separate layers allowed circumventing the scalability trilemma to offer higher throughput while maintaining the initial security guarantees.

The Ethereum ecosystem evolved towards inter-blockchain modularity with rollups like Optimism and Arbitrum, handling execution off-chain. Projects like Polkadot and Cosmos introduced the “blockchain of blockchains,” where various blockchains could interoperate but operate independently.

This Oasis Network review will cover a blockchain network that adopts an intra-blockchain modular design, another flavor in the story of layered architectures attempting to balance scalability, security, and decentralization. Let’s dive in!

Oasis Network Overview

The blockchain industry is evolving towards modular architectures. The ‘rollup-centric roadmap’ solidifies Ethereum as the data availability and security layer of DeFi in which modular execution environments exist as rollups and host smart contract applications.

The Oasis Protocol experiments with three major design themes:

  1. Native modularity – Ethereum is natively monolithic. Rollups achieve modularity with an off-chain network that attests its state transitions to a rollup smart contract deployed on the Ethereum mainnet. The Oasis Protocol offers native modularity. Instead of smart contracts, the blockchain nodes implement modularity at the infrastructure level.
  2. Privacy-preserving smart contracts – Oasis enables verifiable and confidential smart contract execution to promote applications that handle private and sensitive data like social recovery numbers and bank accounts, where the data only concerns a small number of individuals.
  3. Data Tokenization - Leveraging smart contracts to facilitate tokenized private data that maintains privacy and security standards.

Oasis Protocol Background

Dawn Song, a professor at the University of California, Berkeley, known for her work in computer security and artificial intelligence, initiated the Oasis Labs and began working on the protocol. The Oasis Foundation was also created independently of the Oasis Labs to promote the Oasis ecosystem's empowerment, governance, and decentralization.

The Oasis Network is unique in its focus on privacy and data tokenization. The protocol perceives privacy as a tool to mobilize data for analytics in a decentralized setting rather than obscure transactions to hide a user’s identity. Oasis Protocol seeks to enable selective sharing so that individuals can monetize their data while retaining its access and privacy rights.

The Oasis team launched the private testnet in 2018 and the public mainnet in 2020 after multiple audits, bug bounties, and network upgrades. The protocol is backed by esteemed venture capital firms and investors like Binance Labs, Polychain Capital, Pantera, and Andreessen Horowitz (a16z).

What is the Oasis Protocol?

The Oasis Network is designed as a privacy-focused, layer-1 Proof of Stake (PoS) smart contract capable decentralized network compatible with the Ethereum Virtual Machine (EVM). It deploys a modular, multi-layer architecture with a separated consensus and execution layer (called ParaTime Layer).

The Oasis network design is akin to the rollup architecture. In the Ethereum ecosystem, rollups are high-throughput execution environments. They package their rollup transactions into bundles and submit them to the Ethereum mainnet to make that data available during the Ethereum consensus and thus borrow its security. Rollups use smart contracts deployed on the mainnet to their blockchain data. This design is linearly scalable, meaning we can add new rollups for better scalability or add new functionality without affecting the operation of other rollups, and all rollups are processed in parallel.

The Oasis network offers high scalability using a similar design. The Oasis blockchain mainnet is a Proof-of-Stake network offering consensus and data availability to the ParaTime layers. The ParaTimes are where smart contract functionality occurs, with all the parallel execution and linear scalability of Ethereum.

Oasis Network Architecture

The Oasis Network technology comprises the following major components:

The Oasis Network Consensus Layer

The Consensus Layer forms the foundation of the Oasis Protocol and performs the following essential functions:

  • It accepts values from the ParaTime layer and writes them on the consensus layer.
  • It performs ParaTime and validator selection.
  • Consensus layer native token operations.

The Consensus layer is the security layer of the Oasis ecosystem. Each block comprises a limited number of ParaTime layer transactions, providing them finality by accepting and storing their data during block production. Note that the Consensus layer does not attempt to interpret the complex workloads of the smart contract logic, like the generated values or the computations executed within the ParaTime layer. Instead, it is more about ensuring those transactions' overall security and finality

While the ParaTime layers handle the execution of transactions, the Consensus layer deals with transaction ordering and integrity to ensure a secure architecture.

The Consensus layer also handles the ROSE native transactions executing on the base layer. The Consensus layer is a Proof-of-Stake network running on the Tendermint core, but its simple functionality allows Oasis Protocol the liberty to replace it with other consensus models, like Lira HotStuff, if required, with minimal impact on the modular system.

ParaTime Layer

The ParaTime layers are where smart contract execution occurs. The Consensus layer can support multiple ParaTimes that can operate parallel runtimes. Like Ethereum hosts several rollups like Optimism and Arbitrum operating in isolated silos, the state transitions of one ParaTime do not affect the others.

ParaTimes execute state computations and commit the result to the consensus layer, which stores a canonical summary of these state transitions. Like any blockchain protocol, the ParaTime also runs on nodes. These nodes process transactions from clients and register on the consensus layer to participate in the operation of the desired ParaTimes. 

This participation enables protocol-level integration of the ParaTimes and the consensus layer, which Oasis believes is more efficient than other modular designs, like Parachains and sharding.

ParaTime Operational  Model

  1. The ParaTimes are created by developing their code and specifying their metadata. Each ParaTime is allocated a runtime identifier during registration.
  2. A Node operator runs the ParaTimes to execute its procedures. They process transaction requests from clients. They also maintain adequate space to store ParaTime state. The validator nodes that run ParaTimes and the ones that store the state may also be different.
  3. Such a node operator then registers on the consensus layer.
  4. A client can submit ParaTime transactions by publishing the transactions to the appropriate node on the consensus layer that runs the corresponding ParaTime.
  5. The consensus layer finalizes the transactions after verifying that the computation was performed correctly.

Separated consensus and execution layers allow multiple ParaTimes to scale without worrying about security and enable parallel processing of different ParaTimes together. Oasis can host different kinds of ParaTimes to address various use cases. One such application is hosting EVM-compatible ParaTimes to support Ethereum applications or ParaTimes with confidential smart contracts processing to support Data analytics applications. The modular design allows the ParaTimes to update independently of the consensus layer or other ParaTimes.

Oasis Network ParaTime Layers

The Oasis core developer team has already developed three ParaTimes on the network:

Oasis Network Emerald EVM Compatible ParaTime

The Emerald ParaTime layer is an Ethereum Virtual Machine (EVM) compatible blockchain network in the Oasis Network. Emerald is built to integrate Ethereum-compatible smart contracts on Oasis easily. Here are the key features of Emerald:

  • Fully EVM-compatible
  • High throughput and low fees
  • Scalable. With an average block time of just under 25 seconds, Emerald can boast high throughput and low transaction fees.
  • Decentralization – Emerald is operated by a decentralized node network that secures the network with ROSE as the settlement currency.

Oasis also runs a reward program for node operators on Emerald. The ParaTime releases on-chain tokens to reward validator nodes for participating in the network. The program rewards up to 24 ROSE tokens per day to each node. The two-year-long reward program began in November 2021.

Oasis Network Cipher Confidential ParaTime

Confidential smart contract execution is one of the primary deliverables of the Oasis Network. The Cipher Confidential ParaTime layer supports high throughput smart contract execution privacy where nodes use a Trusted Execution Environment (TEE) computing technology. 

Trusted Execution Environment works like a hypothetical black box for smart contract execution, where the encrypted data enters a secure enclave with the smart contract. The encrypted data is then decrypted inside the enclave to prime it for processing by the smart contract code. Finally, the results are encrypted before they are sent out from the enclave so that data remains confidential.

Data Confidentiality in the Oasis Network.jpg

Cipher ensures that the data is never leaked to node operators, application developers, or any third party. Confidentiality is vital in introducing data management services in a decentralized setting. For instance, an application developer on the Oasis protocol may use personal or sensitive data like social security numbers, financial or health information, or geographical records as processing inputs. Confidentiality of such data concerns the data owners and does not obscure the security or openness of the blockchain protocol. 

With Oasis, general users like you and I can monetize our data in a secure and private environment while retaining complete control over its access and use at the same time.

The Oasis network offers further modularity by enabling developers to use other privacy-preserving technologies like Zero-Knowledge Proofs to power private enclaves, enabling customizable confidentiality to developers.

Tokenized Data – Oasis enables the new paradigm of data tokenization, where the protocol ensures that data remains private and inaccessible without permission. Allowing for confidential computing of private data creates a new kind of digital asset that can be consumed along with specific guidelines of use for a fee. For instance, this model is helpful for training machine learning software that requires a lot of data, which is often private.

Oasis Network Sapphire EVM Compatible Confidential ParaTime

Oasis Network introduced the Sapphire ParaTime layer to bring the functionality of Cipher and Emerald together with near-instant finality. Sapphire is an EVM-compatible environment for executing confidential smart contracts. Developers from Ethereum that require high levels of privacy to enhance the use cases of their applications can leverage Sapphire without incurring a lot of additional overheads associated with switching platforms.

Oasis Network ROSE – Tokenomics

ROSE is the native utility token in the Oasis Network. On the consensus layer, ROSE powers staking and delegation, used to pay transaction fees for transfers on the mainnet as well as for fees for smart contract execution on the ParaTime Layers. 

Token Distribution

ROSE Token Allocation.jpg

ROSE has a fixed supply of 10 billion tokens, with a circulating supply of about 6.5 billion in October 2023. Here’s how the Oasis team allocates the liquidity:

  • Protocol backers were sold tokens prior to the mainnet launch.
  • The core contributors received ROSE as compensation for their efforts.
  • The Oasis Foundation received some tokens as an endowment for the development of the Oasis Network.
  • The community and ecosystem allocation will fund programs that stimulate the community, like developer grants and incentives.
  • The key strategic partners of the Oasis Ecosystem are funded for their services.
  • Staking rewards are paid out to on-chain stakers and delegators for contributing to the security of the Oasis Network. The protocol will calculate rewards based on block production, node participation, and staking patterns to disperse the rewards over four years.
